The Lowdown
Alright, Rusty here again. Let’s talk Kennebunk Beach.
Honestly, the first week is a dud. Tiny waves, junky wind, nothing but choppy, weak little slop. You’re looking at swell barely reaching 3 feet, with short periods and lousy onshore wind. Don’t bother. There’s a big gap of over a week with nothing worthwhile.
Then things perk up a little around the start of September. Tuesday the 1st goes glassy in the morning with a long period 15-second groundswell from the southeast. Swell is small, only about 2 feet, but the energy is decent (189). The waves will be cleaner but still small. Crowds are possible out there.
Wednesday the 2nd morning is better, with a light offshore breeze and 3-foot swell from the southeast. The energy is moderate (226). Surfable but nothing to write home about.
Here’s the best shot: Thursday the 3rd afternoon. That’s the standout. A moderate offshore wind from the north-northeast cleans up a 4-foot southeast swell with a very long 15-second period. Energy is strong (817). That’s the session to aim for, even if the beach setup can make that long period a little straight.
Friday the 4th runs a bit bigger, pushing 5 feet, and winds pick up. That one’s for experts only with very strong energy (1240). Not a beginner’s spot that day.
After that, it fades back to cleaner but smaller waves through the second week. A few clean mornings on the 5th, 6th, and 7th, but nothing exceptional.
So if you’re picking, Thursday the 3rd afternoon is the one. Water’s about average temperature for the season, around 65-66°F.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
